In this system extraction bed is fixed and flow direction is usually up to down for easily cleaning of analytes.
Subcritical water extraction equipment.
However the major challenge among the whole process lies in this step which account for 50 80 of the total production cost in terms of energy and equipment.
For example the cannabissfe a supercritical co 2 extraction system from supercritical fluid technologies is able to perform both at subcritical for terpenes and supercritical levels for cannabinoids with simple setting adjustments flexibility and scalability in throughput are always.
To accomplish this process conditions are carefully controlled so that the decomposition of the starting material is limited and directed.
Superheated water is liquid water under pressure at temperatures between the usual boiling point 100 c 212 f and the critical temperature 374 c 705 f it is also known as subcritical water or pressurized hot water superheated water is stable because of overpressure that raises the boiling point or by heating it in a sealed vessel with a headspace where the liquid water is.
